CHARLES IVIACHACEK, JR., OF TABOR, SOUTH DAKOTA.

CORN-SHELLER.

To all whom it may concern:

Be it known that I, CHARLES MACrracnK, Jr., citizen of the UnitedStates, residing at Tabor, in the county of Yankton and State of SouthDakota, have invented certain new and useful Improvements in Corn-Shellers, of which the following is a speciiication.

This invention relates to corn shellers, and has for its object toprovide a simple and an effective means for preventing the cobs fromreturning along the elevator of the sheller when they have arrived atthe delivery end thereof. By such an arrangement much of the annoyanceusually found in corn shellers is avoided for the reason that itfrequently happens that cobs will return along the under run of theconveyer belt of the elevator and will enter the buckets of the grainelevator and choke the same, or injure them by becoming wedged betweenthe buckets and fixed parts of the machine.

In carrying out the invention, I provide fingers of peculiarconfiguration which are adjustably located at the delivery end of t-hecob elevator trunk and which have portions that extend up under therotating members that carry the chain belts and eX- tremities curved ina downward direction from the said upcurved portions and eX- tendingaway from the elevator belts.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawing, in which:

Figure 1 is a longitudinal sectional view of a corn sheller with theimproved attachment applied; Fig. 2 is an enlarged detail sectional viewthrough the attachment; Fig. 3 is a perspective view of the attachment.

Corresponding and like parts are referred to in the followingdescription and Vindicated in all the views of the accompanying drawingsby the same reference characters.

To better understand the invention it is illustrated applied to a cornsheller indicated at l which is provided with an elevator trunk 2 alongwhich chain belts 3 are Specification of Letters Patent.

mounted for movement. At the upper end of the trunk 2 the belts 3 passaround disks or wheels It which are mounted upon a driven shaft 5, anysuitable means being provided for driving the said shaft. A cross bar 6is located at the upper end of the trunk 2 under the shaft 5 and thewheels 4..

The devices for preventing the return of the cobs along the under runsof the chain belts 3 consistl of fingers which are mounted upon thecross bar 6. Each finger is provided with a shank portion 7 havingelongated openings 8 through which securing bolts 9 pass. The said bolts9 also pass through the cross bar 6 and b v loosening the bolts theShanks 7 may be adjusted in a direction longitudinally of the trunk 2.The shanks 7 are located under the disks or wheels 4.

The material of which the fingers are formed at the rear ends of theshanks is carried up into a hump l0 which extends approximatelyconcentric with relation to the shaft 5 and the wheels 4. From the humpthe material is carried down and away from the wheels i forming a curvedextremity 1l. There is sufficient space between the upper surfaces ofthe fingers and the lqwer portions of the peripheries of the wheels 4tto permit the chain belts with their attachments to pass between, butnot sufficient room to permit the chain belts to carry cobs through thesaid space. Consequently as the cobs are carried up on the upper runs ofthe chain belts 3 to the delivery end of the trunk 2, the cobs will comein contact with the upper portions of the humps 10 and will be knockedfrom the chain belts and will fall down along the curved extremities 11away from the machine. Thus the possibility of the cobs returning withthe lower runs of the chain belts is prevented and the damage to themachine and its parts incident thereto is eliminated.

Having thus described the invention, what is claimed as new is:

l. In combination with a corn sheller having a trunk with belts mountedfor orbital movement along the same, means for preventing the return ofcobs along the trunk consisting of spaced fingers adjustablelongitudinally of the trunk at the delivery end thereof, said fingershaving humps which extend up under the delivery ends of the belts.

2. In combination with a corn sheller having a trunk provided Withchains mounted Jfor orbital movement along the same, means forpreventing the return of oobs along the;

trunk consisting of spaced fingers mounted at the delivery end of thetrunk and havingj humps Which extend up under the delivery ends of thebelts, and Curved extremities extending down from the said humps awayand around the delivery end of the chain belt.

4. ln combination With a corn sheller having a trunk with a chain beltmounted for orbital movement along the same, means for preventing thereturn of oobs along the trunk Consisting of a finger providedat one endwith elongated slots, securing bolts passing through the slots andthrough the trunk, said finger having hump extending up and around 'thedelivery end of the ohaiini'belt ln testimony whereof l :affix mysignature in presence of two Witnesses.
